Eleven species of Cyperaceae collected from central Nepal were karyomorphologically studied. Chromosome counts are reported for the first time to be 2n=42 for Carex cruciata, 2n=44 for C. cruenta, 2n=44 for C. fusiformis, 2n=44 for C. longipes var. nepalensis, 2n=44 for C. myosurus, n=14 for Isolepis setacea, and 2n=ca. 122 for Kobresia nepalensis. The chromosome counts of 2n=46 for C. remota and 2n=44 for Eleocharis kamtschatica are different from those presented in previous reports. The karyotypes of E. palustris (2n=16) and E. tetraquetra (2n=20) were the same as those presented in previous reports. One individual of E. palustris collected from Titigaon, Mustang District, showed 2n=15 chromosomes, which is considered to have been derived by fusion of 2 small chromosomes of the 2n=16 individual, forming one large chromosome.
